2. In hilly areas, hole placement is
recommended. Fertilizers are
placed in 8-10 equidistant holes, 5
cm deep around the base of the
palms and covered with soil.



When To Apply:
 For areas with distinct wet and dry
seasons, those with irregular rainfall
distribution and with sandy soils,
fertilizers are best applied every 6
months in split application ½ at the
start of rainy season and ½ six
months before the end of the rainy
season).
 For areas with uniform rainfall
distribution (1.5-3 dry months),
fertilizers are applied in split
during the 1
st
year and once
annually thereafter.

2. Why Fertilize Coconuts:

PCA surveys indicated that there are
ten distinct classes of coconut
nutritional deficiency in the Philippines.
Coconut areas maybe deficient in N, P,
K, Cl, S and Mg but most provinces in
the country fall under N-Cl deficiency.

Judicious application of fertilizers
increases nut and copra yield by as
much as 230%. A study in Davao City
showed that with fertilizer application, a
coconut farmer can realize a net income
of about 180% compared to without
fertilization.


What Fertilizers to Apply:
In the absence of soil & leaf analysis
of an area/farm, the following fertilizer
recommendation provides the coconut
at its different growth stages and
production with four most needed
nutrients (N, K, Cl, S) in many coconut
areas in the country.





Organic Fertilizers:
Green manure like ipil-ipil and farm
organic wastes such as manures of cattle,
carabao, pig, goat, chicken, compost and
night soil can be used to replace part of
the commercial fertilizer requirements.
Coconut crown residues as organic
fertilizer and nitrogen fixing legumes
(Flemingia and Desmodium rensonii) can
substitute for AS as N-sources while co-
copeat and husk for chlorine.

How To Apply:
Fertilizer maybe applied in two ways.
1. In flat areas, it could be broadcasted
in the ring weeded area (about 1.0 to
1.5 m radius) around the base of the
palm fol- lowed by
fork-in to incor-
porate the fer-
tilizer into the
soil.
